The current page FileList items are not properly updated when the paging is enabled. Returning to a previously paged folder is properly restored to page 1, but it keeps showing the content of lastly listed page. The issue is reproducible in all explorer modes of the control.

1. Click the ComboBox

2. Select an item in its dropdown

3. Expected: no exception on selection, actual: A "Selection out of range" exception is thrown.

There are missing methods in the TypeScript definitions provided. 

You can find attached a file that illustrates what needs to be updated.

A workaround is to remove the loading sign functionality by placing the following script at the end of the form tag

The second override is necessary only if you use the OnClientDataLoaded event to alter the data and add fields in the data object that do not exist in the server response. You need to rename the OnClientDataLoaded method call to use your actual method name.

You can find an example of both workarounds and their usage attached.

Some additional information:
- If possible, move the tiles out of the AJAX request, as this will eliminate all of the problems. Depending on the actual scenario perhaps you can make sure they are not in an update panel (e.g., position them absolutely on the page while keeping their markup out of the partial postback).
- consider moving any data formatting logic from the event handler to the template. You can define functions that format the code in the template, not only in the event. An example is available in the attached file. Alternatively, you can return the data formatted from the web service.
- consider reducing the time interval for the requests, because after the AJAX request, only 1 of 2 requests will update the tile UI.

In lightweight the issue is not observed:

The Delete and Backspace buttons remain enabled in spell check mode, allowing the client to delete selections inside the Editor's content area.

Steps to reproduce:
1. Open http://demos.telerik.com/aspnet-ajax/editor/examples/spellchecker/defaultcs.aspx
2. Click the Spell check icon
3. Select several words from the content and press Backspace/Delete

Result: The selected content is deleted
Expected: The Delete/Backspace button press is ignored

Images with "*.jpeg" extension are saved as "*.jpg" in a different file even if the "Overwrite" option is checked. 

Steps to reproduce:

A property to handle that would be very convenient. This way developers could be able to restrict the number of rows that the user can type. Something like MaxRowNumber.

Additionally, a property MaxColumnNumber would be also useful to restrict the length of each row. 

The Bold, Italic, Underline, Justify, Indent, Outdent and other commands are not localized in the Undo/Redo dropdowns.

Hi!

I use .resx file to change Gantt labels with italian translation.

Everything works as expected with the exception of the assign resources button in advanced form (see attachment).

I tried to set declaratively with the Localization-AdvancedAssignResources property but it doesn't work.

Thanks in advance.

When AutoSize is enabled on a RadWindow, the calculated width and height of the window can be larger than the actual content requires. The extra size appears as dead space around the content, on the right side for width and at the bottom for height, and is most noticeable when the content or its wrapping container has its own padding or border.

Steps to reproduce:

• Add a RadWindow with AutoSize="true" (any AutoSizeBehaviors).
  
• Set the window content either through a ContentTemplate with inline markup (for example a RadAjaxPanel), or through NavigateUrl pointing to a separate page.
  
• Give the content, or its wrapping container, a horizontal and/or vertical padding or border via CSS.
  
• Open the RadWindow and let it auto-size.
  

Result:
The RadWindow is wider and/or taller than necessary. The extra space is not evenly distributed and shows up as unexpected empty space next to or below the content.

Expected:
The RadWindow width and height should match the actual content size, with the same behavior as before the 2026 Q1 release.

The built-in commands in the RadSpreadsheet context menu does not execute. Commands such as Delete Row, Delete Column, Hide Row, and Unhide Row/Column appear in the context menu, but clicking them has no effect.

The issue is reproducible in the official demo site.

Steps to reproduce

1. Open a page containing a RadSpreadsheet control.
   
2. Right-click a row or column header.
   
3. Select a built-in command such as Delete, Hide, or Unhide.
   
4. Observe the spreadsheet.
   

Actual result
The menu closes, but the selected built-in command is not executed.

Expected result
The selected command should execute and update the spreadsheet, for example, deleting the selected row or column or changing its visibility.

If both the CSRF validation and the Session state is turned off, the pages containing AsyncUpload control will throw a null reference exception.

  <sessionState mode="Off" />

Summary When a RadPane has Scrolling="Y" (or X/Both) and also has BorderWidth, BorderStyle, BorderColor set (either directly on the pane or via the parent RadSplitter's PanesBorderSize), the pane's inner scrollbar does not render/work correctly. The space reserved for the scrollbar remains in the layout, but the scrollbar itself is missing or non-functional, effectively making the pane's content unscrollable.

Steps to Reproduce

1. Create a RadSplitter with a RadPane that has Scrolling="Y" and BorderWidth="3" BorderStyle="solid" BorderColor="blue" (or just rely on PanesBorderSize).
2. Add enough content to the pane so it overflows vertically.
3. Load the page in Chrome (reproduced on Chrome 152).
4. Observe: only the outer document scrollbar appears; the pane's own scrollbar is missing or the reserved scrollbar gutter space is empty, and the content cannot be scrolled within the pane.

Expected behavior The pane's scrollbar should render correctly and remain functional regardless of BorderWidth/BorderStyle/BorderColor/PanesBorderSize settings.

Actual behavior Scrollbar space is reserved but the scrollbar is missing/non-functional when a border is applied to the pane.
